Abstract
The invention discloses a disconnecting link component of an outdoor alternating current high-voltage disconnecting switch. The disconnecting link component is formed by connecting two knife clamping plates and a pin between the two knife clamping plates, wherein each knife clamping plate is produced by punching a copper material once, thus forming a rounded warped flange which is smoothly turned outwards and transitional from a central plate body to two sides, and a central part of a section matched with a dynamic contact is a cambered surface which is symmetrically concave inwards. The technical solution has the technical advantages of excellent impact strength and bending strength, and can avoid deformation after being used for long term; and good point conductive contact is kept between the cambered contact surface and the dynamic contact.
Description
Technical field
What patent application of the present invention related to is to be responsible at power circuit the outdoor AC high-voltage isolating switch that switching turn-offs charged high-tension line, the in particular improvement of the disconnecting link parts of high voltage isolator.
Background technology
The chief component member of outdoor AC high-voltage isolating switch includes base, is fixed on two parallel supporting insulator and disconnecting links of base, the switch contact that two supporting insulator upper ends arrange terminal block and coordinate with disconnecting link.Disconnecting link in existing high voltage isolator generally adopts two straight plate blade configuration, is connected with some bearing pins between two blades, the hinged conductive attachment of its one end and fixed contact, and the other end turn-offs and contacts cooperation with moving contact.Straight plate blade wherein is directly formed by copper bar or copper coin stamping-out, turn up lateral margin and central authorities are all directly tabular, because manufacturing process causes material internal local density difference, in conjunction with its straight plate structure, cause impact strength and the bending strength of this member not high, easy torsional deformation, it can only improve above-mentioned technical performance by increasing sheet metal thickness, and the increase of weight also can make operation performance of as switch decline." switch mechanism that a kind of isolating switch is used " that Chinese patent CN2012206748991 proposes is a kind of of above-mentioned prior art scheme, wherein for improving contacting of disconnecting link and moving contact, blade inner side is provided with convex plane contact, the corresponding groove that forms in its back side, one elastic pressuring plate is fixed on blade lateral surface, and make it suppress end to act in groove, increase elastic pressure, keep the good conductive contact with moving contact.But in fact the conductive contact surfaces of two parts is that the face that cannot reach desirable contacts, and the planar design between elastic pressuring plate and groove, between convex plane and moving contact, because of restrictions such as processing technology and assembly precisions, cause conductive contact performance and standard to differ farther, and structure increased moving the coordinate resistance of disconnecting link with moving contact, weakened the flexibility of switching manipulation.
Summary of the invention
The goal of the invention of patent application of the present invention is to provide a kind of superior mechanical intensity height and conductive contact and switching manipulation disconnecting link assembly of outdoor AC high-voltage isolating switch flexibly that has.The disconnecting link assembly of the outdoor AC high-voltage isolating switch that patent application of the present invention provides, its main technical content is: a kind of disconnecting link assembly of outdoor AC high-voltage isolating switch, by the pin between two cutter holder plates and two cutter holder plates, connect and form, cutter holder plate described in it is characterized in that is made by a punching press of copper material, formation is stuck up edge by the round end of central plate body round and smooth transition of turning up to both sides, is the cambered surface plate body of symmetrical convex with the middle body of the moving contact section of cooperation.
In above-mentioned overall technical architecture, for improving the conductive contact performance between disconnecting link and moving contact, one elastic pressuring plate is fixed on cutter holder plate lateral surface, and it suppresses to act on and coordinates the elbow end that suppresses of section to have the curved end matching with the back cambered surface of this section of cooperation cambered surface plate body.
The disconnecting link component technology scheme of the outdoor AC high-voltage isolating switch of Patent Application Publication of the present invention, there is the technological merit that impact strength and bending strength are good, long-term use is indeformable, its convex contact-making surface and moving contact have kept good some conductive contact, reduce contact resistance, improved electrical contact performance.

Embodiment
The disconnecting link assembly of the disclosed outdoor AC high-voltage isolating switch of the present patent application, it is specifically constructed as shown in structure chart, and this disconnecting link assembly consists of the bearing pin that connects two cutter holder plates 1 between two cutter holder plates 1 and two cutter holder plates 1.This concrete enforcement in structure, between two cutter holder plates 1, at least by the alignment pin 3 of stationary contact hinge 2 and moving contact side, be connected, middle part is provided with strengthens connecting link pin 4, hinge 2 between two cutter holder plates 1 and bearing pin 3,4 are provided with positioning sleeve, assembling keeps spacing, the especially spacing of the moving contact abutting end of two cutter holder plates 1 of two cutter holder plates 1.For providing two cutter holder plates 1 to contact with the good conductive of fixed contact, around the hinge axis hole of cutter holder plate 1, be evenly provided with at least three protruding contacts 8 on hinge axis hole centres circle, and the optimum position of these three protruding contacts 8 is corresponding positions that the crimping of hinge dish spring acts on cutter holder plate.
In this structure, described cutter holder plate 1 is made by a punching press of copper material, whole punching press forms the round end being turned up to both sides rounding off by central plate body and sticks up edge 6, impact resistance and the bending strength of this cutter holder plate structure are greatly improved, and guarantee that it does not occur torsional deformation, changes the phenomenon of even destroying switch mated condition in the long-term switching manipulation of doing repeatedly.The cooperation section 5 that double-pole clamping plate 1 join and coordinate with moving contact, the cambered surface plate body 10 that two cutter holder plate middle bodies of this cooperation section 5 are symmetrical convex, as shown in Figure 6, and preferably sticks up with two round ends the cambered surface that edge 6 is level and smooth arc-shaped transition.As shown in Figure 2, one elastic pressuring plate 7, its one end is fixed on cutter holder plate 1 lateral surface by bearing pin 3, its another suppress the curved end that the back side arc of the elbow end section of having and coordinate 5 cambered surface plate bodys 10 matches, making to suppress identical the suppressing of elbow end acts on cutter holder plate 1, its lasting elastic force has been guaranteed conductive contact performance good between two cutter holder plates 1 and moving contact, and this structure has also been guaranteed without hindrance opening and closing action between disconnecting link and moving contact.
